Details: The Earthquake PUMP-12 - A Unique Passive Radiator Module
Essentially two horn loaded 12-inch passive radiators, the PUMP-12 adds various implementation possibilities to our existing lineup of SLAPS passive drivers.
Earthquake Passive Radiators provide additional bass, without additional amplifier power or enclosure volume. Designed to perfectly complement all good quality long-throw woofers on the market. SLAPS/Pump-12 add up to +6dB of bass compared to regular sealed and ported enclosures. They can be integrated into virtually any sub/cabinet combination.
When using a sealed enclosure, there is one peak of resonant frequency at which the amplifier draws the least current. The graphs below illustrate the difference between a typical sealed box enclosure and the PUMPed box enclosure.
Recommended Box Size:
The PUMP-12 requires 9-in x 14-in x 14-in of installation space. Take the recommended sealed enclosure dimensions of the chosen active driver and add the 9-in x 14-in x 14-in to it. We recommend sanding the cutout hole and pushing the module's dust caps inwards to allows the PUMP-12 to go through the cutout hole without damaging the surrounds.
Pump-12 enables the transfer of high amplifier power into low frequency output. Since the active driver does not have to fight against increasing pneumatic pressure in a closed cabinet or over-excursion close to a port tuning frequency. In a closed cabinet design the pneumatic loading of the woofer increases as a function of its travel, this causes compression. Pump technology possesses none of these limitations.
